Hydraulic system 2.1 – Main storage tank and
secondary tank
Hydraulic system 2.1 is intended for storage tank installations in which
heat is to be transferred from the main tank to the secondary tank.
Heating water and domestic hot water are taken from a secondary
tank. By measuring the temperature difference between the tanks
SmartBio controls the charge pump. SmartBio starts charge pump RO1
when TS1 has reached the set temperature MT or TS2 is below the set
temperature ST. The pump stops when TS3 has reached the set tem-
perature SB, TS2 is higher than TS1 or TS1 is below MT.
If the temperatureTS2 in the secondary tank sinks with the RAO value,
the additional heat source starts with selected delay. Normally charge
pump RO1 is not activated at this point. However the pump can be ac-
tivated in commissioning. The additional heat is activated until the tem-
perature TS2 has reached the temperature ST.
Sensor TS1 is mounted in a sensor pocket in the upper part of the main
tank. Sensor TS2 is mounted in a sensor housing in the upper part
of the secondary tank.
Sensor TS3 is mounted in the lower part of the secondary tank.
N.B! The sensor must not be placed on the supply pipe as this might
disturb the function.
Hydraulic system 2.2 - Main storage tank and
secondary tank with thermic valve
The basic functions are the same as in hydraulic system 2.1 but to
prevent self-circulation and avoid high temperatures in plastic pipes
a ThermoVar thermic valve is to be installed between the tanks.
Thermo Var thermic valves are available with different limit temperatures.

Hydraulic system 3.1 – Heat source and storage tank
Hydraulic system 3.1 is for heating installations where the heat is
transferred from a heat source to a storage tank. When the tem-
peratureTS2 has fallen below the set value ST, SmartBio will activate
the heat source REL. When TS3 has reached the set value SB, the
heat source will be deactivated. Once temperature TS1 has reached
the set value BT and TS1 is above TS2, charge pump RO1 will start.
When TS3 has reached the set value SB, TS2 is above TS1 or TS1 has
fallen by hysteresis CH below BT, the pump will stop. To reduce the
amount of burner starts, the restart delay CRD can be set.
Sensor TS1 is mounted in a sensor pocket in the upper part of the
heat source. Sensor TS2 is mounted in a sensor housing in the upper
part of the storage tank.
Sensor TS3 is mounted in the lower part of the storage tank.
N.B! The sensor must not be placed on the supply pipe as this might
disturb the function.
Hydraulic system 3.2 – Solid fuel heating boiler
with loading unit and storage tank
ThermoMat loading unit ensures a high return temperature to the
solid fuel boiler which increases the efficiency of the system. Tarring
and condensation are prevented which prolongs boiler life. Basic
functions as in hydraulic system 3.1.
